Let's go through each question one by one and solve them with explanations.

1. Which organelle is the command center for eukaryotic (plant and animal) cells?
Answer: D. Nucleus
✔ Explanation: The nucleus contains the cell’s DNA and controls all cellular activities such as growth, metabolism, and reproduction. It directs protein synthesis and regulates gene expression, making it the "command center" of the cell.
---
2. What is the function of a lysosome?
Answer: D. To remove waste using digestive enzymes from the cell
✔ Explanation: Lysosomes contain hydrolytic enzymes that break down waste materials, cellular debris, and foreign particles. They are essential for recycling and cleaning up the cell.

3. Which of the following are prokaryotic cells?
Answer: B. Bacteria
✔ Explanation: Prokaryotic cells lack a nucleus and membrane-bound organelles. Bacteria are classic examples of prokaryotes. Animals, plants, and fungi are eukaryotic.
---
4. Which of the following is a eukaryotic cell?
Answer: A. Plant and animal
✔ Explanation: Both plant and animal cells are eukaryotic because they have a nucleus and membrane-bound organelles. Bacteria are prokaryotic.

5. What is the difference between a prokaryotic cell and a eukaryotic cell?
Answer: A. Prokaryotes do not have a nucleus or organelles, but a eukaryotic cell does
✔ Explanation: This is the key distinction:
-
Prokaryotes (like bacteria): No nucleus, no membrane-bound organelles.
-
Eukaryotes (like plants, animals): Have a nucleus and various organelles.

6. What is the purpose of the nucleus?
Answer: D. It is the command center, contains DNA, and cell division
✔ Explanation: The nucleus houses the genetic material (DNA), controls gene expression, and plays a central role in cell division. It coordinates all major cellular functions.

7. "Post office" of the cell that packages proteins and fats:
Answer: Golgi apparatus
⚠️ Note: This question is incomplete in your image — the answer choices are missing. But based on the description, the correct answer should be:
👉
Golgi Apparatus
✔ Explanation: The Golgi apparatus modifies, sorts, and packages proteins and lipids (fats) for transport to their destinations, either inside the cell or outside. That’s why it's often called the “post office” of the cell.
